Abstract—The results of development of new nickel-base superalloy having an operating temperature up to 800°C for gas turbine disks have been presented. Structures, mechanical properties, and phase transformations of six experimental compositions have been researched. Physical and chemical modeling has been used to make a right choice of an alloy; with parameters as composition equivalents (they were based on equations of nonpolarizing ionic radii). The highest level of strength, ductility, toughness, and heat resistance was exhibited at 750°C by the Ni–Co–Cr–W–Mo–Ta–Al–Ti–Nb experimental composition with the total of aluminum, titanium, and niobium equal to 10 wt % and containing 4 wt % of tantalum.
